Über dieses Buch

This book presents the research and development results on power systems oscillations in three categories of analytical methods. First is damping torque analysis which was proposed in 1960’s, further developed between 1980-1990, and widely used in industry. Second is modal analysis which developed between the 1980’s and 1990’s as the most powerful method. Finally the linearized equal-area criterion analysis that is proposed and developed recently. The book covers three main types of controllers: Power System Stabilizer (PSS), FACTS (Flexible AC Transmission Systems) stabilizer, and ESS (Energy Storage Systems) stabilizer. The book provides a systematic and detailed introduction on the subject as the reference for industry applications and academic research.

Chapter 1. Introduction
Abstract
Power system low-frequency oscillations are the oscillations of active power delivered along particular transmission corridors in a power system with the oscillation frequency from 0.1 Hz up to a couple of Hz. Once started, the oscillations can continue for a while and then disappear, or grow continuously to cause power system collapse. In this book, they are called power system oscillations or power oscillations for short.

Chapter 2. A Single-Machine Infinite-Bus Power System Installed with a Power System Stabilizer
Abstract
The fundamental equations describing the dynamics of a synchronous generator are the well-known Park’s voltage equations.

Chapter 3. Damping Torque Analysis of Thyristor-Based FACTS Stabilizers Installed in Single-Machine Infinite-Bus Power Systems
Abstract
Installation of a shunt thyristor-controlled reactive power compensator, the static VAR compensator (SVC), is for the voltage support at a key location in a power system. An additional stabilizing signal can be superimposed on the voltage control loop of the SVC to provide extra damping to the power system.

Chapter 4. Single-Machine Infinite-Bus Power Systems Installed with VSC-Based Stabilizers
Abstract
Figure 4.1 shows the configuration of a shunt voltage source converter (VSC)-based unit connected to high-voltage transmission line through a step-down transformer. xs is the equivalent reactance of the step-down transformer.

Chapter 5. A Multi-machine Power System Installed with Power System Stabilizers
Abstract
Figure 5.1 shows the configuration of a two-machine power system where two synchronous generators are connected by a transmission line. This simple system is used in this section to demonstrate the procedure of establishing the mathematical model of a multi-machine power system. Later, it will be used for introducing basic concepts and methods in the analysis of power system oscillations and design of PSSs in the multi-machine power system. For the purpose of demonstration, a load is connected at the terminal of two generators and a node along the transmission line, respectively.

Chapter 6. Multi-machine Power System Installed with Thyristor-Based FACTS Stabilizers
Abstract
Figure 6.1 shows an N-machine power system with nodes of internal voltage of generators added. From Fig. 6.1, the following network equations can be established.

Chapter 7. Multi-machine Power Systems Installed with VSC-Based Stabilizers
Abstract
Without loss of generality, it can be assumed that a shunt VSC is installed at a busbar between nodes 1 and 2 in an N-machine power system, as shown in Fig. 7.1. The shunt VSC can be connected to an energy storage system (ESS), a HVDC, or a static renewable power station, such as a photovoltaic (PV) or fuel cell (FC) power station. It can operate alone as a VSC-based FACTS device, STATCOM (see Sect. 4.​1.​1.​1).
